.'1'0 Aall 'whom it may concern:

Be it known that I, CLARENE. W. HoNA- nAeH, a citizen ofthe United States, residing embodied in the invention.. tion on the line A B of F1g.1. Fig is a l -section on the line C D of Fig.`1.

at. Edwardsville, in the county of Luzerne and State of Pennsylvania, have invented a new andV useful..Shaking-Screen, of which 'the following isa s ecitication.

This invention rc ates to the screen structure, as well as to the means for operating the screen, its object beine to piovide a screen which will more 'effect-ua V1y separate the niatcrial, andalso' an Voperating mechanism 4which is cushioned, thus making the motion of the screen more smooth, and rendering. it less liable to breakage and damage.

'lhis screen is designed primarily for separating coal from slate.

lV ith the foregoing objects in view the invention consists in the-'novel construction and arrangement of parts to .be hereinafter described and claimed, referencebeing had to the drawing hereto annexed in which-'- Figure 1 is a side elevation of the screens Fig. 2 is a sec- Fig. et is a section on the line E F of Fig. l.

. is a det-ail view showing the manner of connectingir a hanger to tliesereens. Fig. 6 is an elevation of a modification of the cushioning means hereinafterdescribed. Fig.'7 is a. plan view of -thc screen proper. Fig. 8 is atransverse section thereof. Fig. 9 is a lan` view of a modified' forni of screen. Fig. 1() is an elevation of :mother Vmodification of the cushioning means. Fig. 11 is a Avertical section on the line. 11-11 of Fig. 10. Fig. 12 is avertical section on the line 12-12 of Fig. 10. Fig. 13 is a perspective view of the screen provided with a side discharge. Y

ln the drawings fourscreens are shown which are arranged in pairs "on opposite sides 'of the drive shaft.

The screens are indicated at l, 2, 3 and et,

respectively. Each Screen may comprisef any number coupled in series to form in l' effect a gang, and the members of each pair nected to the screens by meansof armsor rods to impart asliaking movement thereto. The members of each set of screens are arranged one above the other, andvpro'perly spaced apart. Transverseangle bars 7 conneet the longitudinal side-bars 8 of the screens and serve to reinforce tlie'.saine. The screens may be connected in any man ner, and separated in a way to admit of their free movement.

Connecting rods t) couple the screens with of any coi'istruction, but itis preferred to have each formed of a fiatl baror strip of wood or other resilient inaterial in order that the spring action referred to maybe had.

A bloclr l1 is secured to the outer' Sides of Fiiion.

.ings thereof. The connecting rods may .be

theA screens intermediate the ends thereof,

and is formed upon its inner sides with a reduced port-ion l'whicli tits between the longitudinal side bars 8 of the screens, and

serves as a filler or spacci' to lioldtlie screens .l sepa-rated. Bolts 13 pass through the sidel bars, and through the spacer 12, and connectl all together. One of the ends of the connect. ing rod t) is attached to the block 11, and,

since it is preferred to. provide eac-li set/of' screens witi four connecting rods, bolts 14 are employed for connecting the-upper and lower connecting rods to the ,upper and lower faces of the blocks l1.

It will be' noted that this construction throws the con-'f necting rods to one side of the screens, so

as netto interfere withv the screens when in operation. lt is not absolutely necessary to connect the rods 9 to the middle portion of the screens, ,but this arrangement is preferable. 'l Y The eccentric strap is formed of similar parts or sections which are tittcd about the eccentric (S and secured thereto. Each' strap .section is formed ivitli an upper and a lower flange 15, to which the upper and lower connecting rods 9 are res ectively secured by bolts 1G uor other suita le fastening means. Theupper and lower tianges arecoiinected by an intermediate web 17, and each'stra i section has an o t-standing lug 18 which is provided with bolt -holes tp receive the bolts l or other fastening meansby*ivhichv-the'vftuio.

" v sections .are joine v By connecting the rods 9 to the eccentric strap sections as hereindescribed,.said rods stay each other, and prevent the. strap sections fromA being' connected too .tightly-to-h the eccentric, thus preventing breakage of with u buffer, or yieldingmeans'to prevent l injuriouscpntact of the rods 9 therewith. The buil'er comprises a tube 19 secured in a transverse opening at' the reduced end of the block-.springs 'O arranged above and be-A low the tube 19,4 and shoes :'21, thelatter' hav-y ing' stems lwhich projlr-.ctinto Vthe outer .ends of' the springs '20. so as 'to retain the parts in place. The shoes are flanged', and' may be protected by'a lining of rubber` felt or the like to nevent injury to theronnect- 'ing rods 9 during the operation vot the machine H f Hangers support the st reens.and are vco'nnected at their upper ends -to beams -or supports :24, and aremade fastr at their lower ends to the screens. The hangers vmay be of any construction, and are-preferably resilient. so as to also Vassist in the shaking action of the screens. Angle irons or bracki, withithc longitudinal side bars'Softhe ets 25 connect thc lower ends of the hangers screens.l `The angle iron 25 yof onev pair ofhangers may beseeured to the screens bythe .bolts 13, and those of the other hanfgers by the bolts or fastenings 26 employedA orcon-` necting -the screens to one another, and to interposed spacing blocks 27 at the ends lthereof. Butler means 2S arel interposed between the upper ends of the hangers and their supports 2l, and consist of springs. Portions of the supports 25 opposite tothe' upper cndsof the hangers arelcut'awayto permit of said hangers having sutiiclent )la I .vr j. 7..; l Iii the modification shown in Figzf the rods 9 are secured tofthejfront 'endfof the screen vor that end nearest to the shaftV 5,

The f l'liletion of the spring. strip 31 is' the same as thesprmgs 7.10 and their, associate parts.

The vconstructionofthe st :reen proper is shown in Fxgs. `Tand 8.a moditicatlon be@ ing shown'dnA Fig. 9. Said screen comprises "a plateg having -l'ierforations 34,*aud diaglcorrugationsextend in `opposite directions I onfally extending corrugations p' These 'the' upper .l
